Recovering from a disaster!

The following recipes will show how to fail over to the mirrored data on the backup cluster after the primary cluster ceph has encountered a disaster and how to failback once the ceph cluster has recovered. There are two methods for failover when dealing with a disaster:

  • Orderly: Failover after an orderly shutdown. This would be a proper shutdown of the cluster and demotion and promotion of the image.
  • Non-orderly: Failover after a non-orderly shutdown. This would be a complete loss of the primary cluster. In this case, the failback would require a resynchronizing of the image.
